Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus; precision instruments and apparatus; parts and accessories thereof. This chapter has a broad scope, ranging from spectacles and microscopes to medical equipment and measuring instruments. The core characteristic is that these goods are usually precision-made and technologically complex, used for professional purposes such as measurement, inspection, analysis, and medical treatment. Within the chapter, they are divided by function into multiple headings, such as 9018 for medical and surgical instruments, 9027 for physical and chemical analysis instruments, etc. Heading 9018 covers instruments and appliances used in medical, surgical, dental or veterinary sciences, including scintigraphic apparatus, other electro-medical apparatus and sight-testing instruments. Specifically, it includes: instruments for internal medicine, surgery, dentistry, and veterinary medicine, such as scalpels, syringes, endoscopes, electrocardiographs, ultrasound diagnostic apparatus, X-ray equipment, etc. The core of this heading is medical devices used for diagnosis, treatment, and surgery, whether or not electrically driven. However, note that some devices, if they have an independent function and are not specifically named, may be classified under other headings. Code 901814 is a 6-digit subheading. The first 2 digits '90' represent Chapter 90 (optical, medical, etc. instruments). Digits 3-4 '18' represent heading 9018 (medical and surgical instruments). Digits 5-6 '14' represent subheading 9018.14, which in HS2017 is 'endoscopes'. Further subdivision: under 9018.14 there may be more detailed statistical subheadings, but internationally it is uniform at 6 digits. Therefore, 901814 refers to endoscopes, including vehicle-mounted endoscopes. A vehicle-mounted endoscope is an application form of an endoscope, used for vehicle inspection, but in essence it is still an endoscope, so it is classified under this subheading. A vehicle-mounted endoscope is a type of endoscope. An endoscope is a medical instrument used to examine the interior of the human body or narrow spaces. Even when applied to vehicle maintenance, its core function is still optical inspection, which conforms to the description of heading 9018 'medical and surgical instruments'. It should not be classified under 9027 (physical and chemical analysis instruments) or 9031 (measuring or checking instruments), because the main function of an endoscope is visual inspection rather than measurement and analysis. It is also not classified under 8525 (image capture equipment), because it is a complete endoscope system, not merely a camera.

Product name: Declare the commodity name, which should be accurately described as 'vehicle-mounted endoscope' or 'industrial endoscope', and indicate the use. Use: State the specific application scenario, such as 'for internal inspection of vehicle engines, fuel tanks, etc.', to distinguish it from medical use. Brand: Declare the brand name (such as Olympus, Bosch, etc.); if there is no brand, fill in 'no brand'. Model: Fill in the specific model, such as 'XX-100', to facilitate identification of product specifications. Working principle: Briefly describe the working principle, such as 'optical fiber image transmission' or 'electronic imaging', highlighting the characteristics of an endoscope. Whether electrically driven: Indicate whether it is powered, such as 'electric' or 'non-electric', which affects subheading subdivision. Composition: Explain the main components, such as 'including probe, display screen, cable', and whether it is a complete system. Product name: vehicle-mounted endoscope; Use: for internal inspection of vehicle engines and fuel tanks; Brand: XYZ; Model: XYZ-200; Working principle: electronic imaging, transmitting images to a display screen through a flexible probe; Whether electrically driven: electric; Composition: probe, control unit, display screen, connecting cable. Mistakenly classifying a vehicle-mounted endoscope under 8525 (cameras), because it has a camera, but an endoscope is a complete inspection system and should be classified under 9018. Failure to indicate industrial use, causing it to be mistaken for a medical endoscope; although it is classified under the same code, this may affect regulatory conditions. Ignoring the declaration of brand and model, causing delays in customs valuation or intellectual property verification.

Core basis for classification: An endoscope is a medical instrument used to examine the interior of the human body or narrow spaces. Even when applied to vehicle maintenance, its core function is still optical inspection, which conforms to the description of heading 9018 'medical and surgical instruments'. According to HS notes, 9018 includes endoscopes, whether or not for medical use. Although a vehicle-mounted endoscope is used for industrial purposes, because its principle and structure are the same as those of a medical endoscope, it is classified as an endoscope under 9018.14. If it were purely image capture equipment, it might be classified under 8525, but an endoscope usually includes illumination, transmission, and other systems, so it is not classified under 8525. 8525 Cameras, camcorders: 8525 covers television cameras, digital cameras, etc., whose main function is shooting and recording; whereas an endoscope is used to observe areas that cannot be directly seen and usually includes illumination and transmission systems, with the function of inspection rather than recording. 9027 Physical and chemical analysis instruments: 9027 is used to analyze material composition, physical properties, etc., such as spectrometers and pH meters; an endoscope is only used for visual inspection and does not perform analytical measurement. 9031 Measuring or checking instruments: 9031 covers instruments for measuring length, angle, etc., such as micrometers and projectors; an endoscope is mainly used for visual inspection and does not directly measure dimensions. 9013 Liquid crystal devices, lasers: 9013 includes lasers, telescopes, and other optical elements; an endoscope is a complete instrument, not a separate optical element. Is it clearly an endoscope rather than an ordinary camera? Is it used for vehicle inspection but with the same principle as a medical endoscope? Does it include illumination and transmission systems? Could it be classified under 8525 because it has a camera function? Have the brand, model, and working principle been declared?

Why is a vehicle-mounted endoscope classified under 901814 rather than 8525? Although a vehicle-mounted endoscope has a camera, its core function is to inspect areas that are difficult to observe directly, and it usually includes illumination, transmission, and display systems, so it falls within the category of endoscopes. HS code 9018 explicitly includes endoscopes, whether or not for medical use. In contrast, 8525 mainly covers cameras used for shooting and recording, which do not have the inspection function of an endoscope. Therefore, based on function, a vehicle-mounted endoscope should be classified under 901814. Are endoscopes under 901814 limited to medical use only? No. The notes to HS code 9018 indicate that endoscopes include both medical and non-medical uses. Endoscopes under subheading 901814 include both medical endoscopes and industrial endoscopes. Therefore, a vehicle-mounted endoscope, as a type of industrial endoscope, is also classified under this code. However, note that different uses may affect regulatory conditions and tax rates, and the use should be truthfully declared. What key information is required when declaring a vehicle-mounted endoscope? When declaring, the following must be provided: product name (vehicle-mounted endoscope), use (vehicle inspection), brand, model, working principle (electronic imaging or optical fiber), whether electrically driven, and composition (probe, display screen, etc.). This information helps customs classify accurately and avoids delays or disputes caused by incomplete information. If the vehicle-mounted endoscope is wirelessly connected to a mobile phone, does the classification change? Wireless connection does not affect classification. As long as its core function is endoscopic inspection, it is still classified under 901814. However, if the device is merely a camera module displayed through a mobile phone and has no independent illumination and transmission system, it may be regarded as a mobile phone accessory and classified under 8517 or another code. Therefore, judgment must be based on the actual composition of the product. How can the tax rate for 901814 be checked? Tax rates vary by country, trade agreement, and annual adjustments. It is recommended to check the 'Customs Import and Export Tariff of the People's Republic of China' issued by the General Administration of Customs of China or confirm through the customs classification advance ruling system. You may also use the tax rate query tool on the official website of the General Administration of Customs and enter HS code 901814 to obtain the latest tax rate. If a vehicle-mounted endoscope is exported to the United States, is the HS code the same? The first 6 digits of the international HS code are uniform worldwide, so in the U.S. HTSUS, 9018.14 is also endoscopes. However, the United States may have a 10-digit statistical code, with the last 4 digits used for statistical purposes. When exporting, the U.S. HTSUS code must be used; the first 6 digits are consistent with 901814, and the last 4 digits must be determined according to the U.S. tariff schedule. If an endoscope is used for medical purposes but is actually vehicle-mounted, what are the consequences of false declaration? False declaration may lead customs to determine a classification error, affecting tax rates, regulatory conditions (such as medical device registration), and trade statistics. If it is determined to be tax evasion or evasion of regulation, it may result in fines, cargo detention, or even administrative penalties. Therefore, the use and function must be truthfully declared. How can one determine whether a product is an endoscope or an ordinary camera? An endoscope usually has a slender probe, illumination system, image transmission, and display device, and is used to observe narrow spaces; an ordinary camera is mainly used for shooting and recording and does not have a probe and illumination transmission system. If the product is merely a small camera without independent display and illumination, it may be classified under 8525. It is recommended to refer to the product manual and functional design.
